Abstract: 1,053,950. Regulating fluid flow. EATON YALE & TOWNE Inc. May 17, 1965 [Aug.3, 1964], No.20794/65. Heading G3H. [Also in Divisions F1 and F2] A fluid metering assembly e. g. for controlling lubricant flow in valve gear, comprises a valve plate 35 held in engagement with a conical valve seat 34 by a spring 37 so as to be tilted in relation to, and partially obstructing passage way 33 thereby metering fluid flow. When arranged in a hydraulic valve tappet 7, the reservoir 19 communicates with a lubricant supply passage 22 through inlet 21, recess 29 and passage 20. Lubricant metered through passage 33 passes through push rod 9 to the valve rocker gear. Clearance in the valve gear is taken up when pressurized lubricant in reservoir 19 passes through passage 25 and check valve 24 into pressure chamber 23 to move plunger 17 relative to tappet 7. During the valve opening stroke, check valve 24 is closed and leak takes place from chamber 23 between the adjacent walls of plunger 17 and tappet 7. During reciprocation cam 5 imparts a rotary motion to tappet 7 which is transmitted to spring 37 which, because of its non-axial engagement with plate 35, causes the plate to rotate thereby removing foreign matter from the valve seat. In modifications the valve seat may have an annular groove 34a Fig. 7a (not shown) or may be a bimetallic disc arranged to increase the flow at lower temperatures. In other embodiments the spring 36 is replaced by a short spring 39, Fig. 3 (not shown) having its lowest coil engaged in an internal groove of plunger 17 or is replaced by a hollow cylinder formed with a resilient projecting finger 44, Fig. 4 (not shown) which engages the valve plate 35. In a further embodiment a planar disc 50, Fig. 5 (not shown) supported by a spring and having a projecting resilient finger engages the valve plate 35. In modifications of this embodiment either the supporting spring or the planar disc itself may be engaged on a ledge or circumferential groove. In further embodiments the valve plate 35 is replaced by a planar disc having two projecting resilient fingers 51, Fig. 6 (not shown) or an annular rim 52a, Fig. 6a (not shown) with a projecting planar disc 51a, the disc or rim being engaged on a ledge or groove of the plunger 17. The fluid metering assembly may be in a mechanical tappet.
